I am in the process of full-stack engineering a web application. As the front-end framework I want to use React. I've learned JSX and I'm ready to build components; however there are many other frameworks and complications going in with React.
I am using express.js for routing and passport.js for securing the routing process. However, looking at several tutorials and forums I keep seeing other routing handling methods such as React Router.
My question is as follows, may I use React.js as a variation of templating engine? In other words, I'll use EJS for dynamically serve HTML and use React's component based approach to "texturize" the served markup. Is this possible or do I have to use React Router or some React features such as React history etc.?

I am working on a react app with mapbox that gets data from a JSON file and adds the data on the app.. I have successfully built the app. But what I want now is that I want to be able to use my react-app as a web component. In a way that it will be usable in websites and web apps.
Think of it this way:
Your React application is the U-Haul truck that delivers everything from the Web Server (Back-End) to the Browser (Front-End)
Now you say you want everything wrapped in a (native) Web Component:
<move-house></move-house>
It is do-able, but you as the Developer have to develop all dependencies
It starts by fully understanding what React is and does, so you can wrap all its behaviour.
Unlike other Frameworks (Angular, Vue, Svelte) React has no "Make-it-a-Web-Component" option,
because React, with its virtual DOM, is a totally different (and rather outdated) beast that doesn't comply with modern Web Standards. (today [Dec2020] React only scores 71% on the Custom Elements Everywhere test)
See: https://custom-elements-everywhere.com/libraries/react/results/results.html
for what you as the developer have to fix, because React does not do that for you
Some say React compared to modern JavaScript technologies, Frameworks, Web Component libraries like Lit and Stencil or Svelte, is more like:
It is possible in react using direflow. https://direflow.io/
I am new to ReactJS and I'm working on the Front-End side of a project I have developed myself. The project is meant to be a site where users can logIn and post messages.
I have developed my back-end using Spring, Kotlin and MongoDB as DDBB, and have developed the API to perform all the necessary actions.
I have already developed the front-end side in Angular 6, since I know how to do that, and I have the site running correctly.
However, I'm trying to learn ReactJS, and I want to 'replicate' what I've done in Angular with React. After some tutorials and stuff, I have been able to develop my LoginComponent, which can fetch correctly the userInformation from the backend.
Here's then my question: In Angular, I use services to store variables that I may need from different routes, such as the userId (I will query the messages using that). I have not noticed how to do that in React, any idea?
Sorry for the poor explanation, I'm new to React.
You need a place to store the application state, you can use rxjs or mobx observables, or you can use redux. I personally like observables, as there is a lot of boilerplate in redux.
In react, your smart components will usually import pure functions from services that perform actions on the stores, and derive its rendering from the application state that is passed down to dumb rendering components.
how to create web and android application using react. can I use both reactJs and react native. If I create web app by using reactJs, how to convert web into android application (reactjs into react native).
Thanks in advance...
I personally in my projects have not seen a way of doing this automatically. There are some things that you might wish to look at however.
https://github.com/necolas/react-native-web - Seems to allow you to use the same components from react native directly in a react project. So the idea being you write your react native project and then import this package for the web build and voila.
I have ended up manually managing the proccess. If you layout your application keeping your application logic completely seperate from any display component logic the process really isn't that painful. Not sure if there is a better guide but this might give you an idea http://jkaufman.io/react-web-native-codesharing/
You could also use something like webpack to automate this process of swapping components / packages out for native / web.
I have a full blown mobile web app using the following:
React
Redux
Redux-React
React Router
Firebase
I eventually want to convert this mobile web app to a mobile app and I am looking into using React Native. There is a lot of literature on how to build React Native apps from scratch or to convert a native app in Objective-C to react native but I am struggling a bit to find some prior-art of how to approach taking a mobile web app towards native.
More specifically, what are the things that wont work out of the box? I am looking at React-Router.
Some thoughts around how to start transitioning, what to touch and what to not worry would be very helpful.
UPDATE:
Imagine the following app structure. Its already a lot of code. So, I am wondering if there are approaches to do this incrementally?
Many folks are porting their React applications to React Native incrementally by using Web View as an initial 'foot in the door', and then using React Native views on a flow-by-flow basis. With the recent availability of react-native-webview-bridge ( https://github.com/alinz/react-native-webview-bridge ), two-way communication between those web views and the react native components is now very easy.
There can be performance issues when using Web Views on iOS versus the regular Safari app, so that may force certain UI flows to be converted to React Native before you can ship.
I'd highly recommend translating any Selenium tests to Appium to keep your automated test coverage up. React Native is still a bit volatile, and being able to upgrade quickly and safely will be highly dependent on having an automated test suite.
Be sure to have your API (is you have one), your reducer and your action outside of your web folder, because you'll be able to use them in your mobile app.Most of your app structure will be the same, except for the react-router. Like Jan Fanz Palngipang, you could use react-native-router-flux (which is the one i'm using)
I would recommend you to check starter kit like nativebase, rReact Starter Pro to see how their drawer is working.(see how they change container)
I'm a newbie for React Native and I don't have native development experience(I only worked on several hybrid apps), while learning this react native framework, I get several questions which block my learning.
How to navigate from one page(component) to another page(component) without relying on navigatorIOS or navigator component? In Hybrid develop mode, it's so easy, just add element A with href attribute would work, but in React Native, how to do it? I read some examples, they all use navigator or navigateIOS component to do it.
Is there any interceptor mechanism in react native so that we could inject some logic before rendering or loading component, for example, we want to have interceptor to check whether user has been login?
How to save data globally (cross components)? In Hybrid mode, we have session, we have local storage, and if we angular JS framework, we could use Service or root Scope to save data, by using react native, how do we save data cross components?
Since I'm new to react native and new to native application development, these questions might be fairly stupid, if anyone could help on this.
I don't know i'm answering to your question but please check this router component for react
https://github.com/rackt/react-router
ComponentWillMount and ComponentDidMount can be used to perform some initial loading
You can use flux framework along with React which can do almost all like in angular js
